of the load to the truck frame, and likewise change the points of connection between truck irai'ne and the locomotive frame as may be required under variable condi* e tions. f

ln Figs. (l to 9 inclusive we have indicated the points of application ol? the load with the letter L, and the pointe of sup pori. or connection between said truck 'frame and locomotive frame with the letter S.

it will be readily understood that .minor changes in the eine, form and construction ol' the various parte of our improved trailer tru-3k can be made and substituted 'for those herein shown and described, without departing from the spirit ci? our invention, the Scope of which is set forth in the appended claims. claim: l. The combination with a locomotive frame, of a trailer truck traine pivotally connected to the locomotive traine. springs bearing upon the journal boxes of the trailer truclo the forward ends of which springs are connected to the trailer truclrl frame and the rear ends oit which springs support the rear poi l fof the locomotive frame and caril tlierelnf7 and friction elements in/epoeel between the rear portions of the ell li the contacting parts of the loconor ve ironie. v

" i combination with a locomotive a trailer truck frame pivotally i to the locomotive iframe, springs he joiirnallboxes of the trailer connecting the forward poririnogs witlrthe vtrailer truck r portions ot which springs rear portion oi' the locomotive rte Carri d thereby, anx equallvar Iy Supported on the locomo- -ime above the Yforward portion of the truc; iraniea and a connection besaid equalizer bar and the forward trailer truck frame.

o-J-inbination with a locoiiocl'iire :i-'trailer truck ,trame pivotalhV to the locomotive frame, springs ,A `n the journal boxes of the trai lie forward pori ai 'with the trailer truck rear portions; ol? which Springs i e rear porton. of the locomotive N carried thereby. a'i equalth e . the forward portion of the eine connection betrl 'r and ille :forward end or iler truer; iframe, and a. removable arranged between. the locoi and trails truck llrauie.

"o corali/inutile; with a locomotive L ailer truck 'trame pivotallv L, locomotive traine, springe "our-nal boi-:es oi the trailer qlvsuoported on the loconioA truck, hangers connecting the forward por tions of said Springs with the trailer truck framev the rear portions of which springs support the rear portion oi the' locomotive frame and parts carried thereby, an equal-` izer bar yieldingly supported on the lucianotive frame above the iorward portion oit the trailer truck trame7 a connection between said equalizer bar and the forward end of the trailer truck trame, and side bearings removablyY positioned between the loco motive frame and trailer truck frame.

5. The combination with a locomotive frame, of a trailer truck frame, a hanger supporting the forward end of Said truck frame7 which hanger is yieldingly support= ed upon the locomotive frame, Springs bear* ing upon the journal boxes 'of the trailer truck frame, connections, between the forward ends of said springs and the trailer truck framea and the rear ends of which springs support a portion of the locomotive frame and parte carried thereby.

6. The combination with a locomotive frame, of a trailer truck frame, a hanger supporting the forward end of said truck frame, which hanger is yieldingly supported upon the locomotive frame, springs bear ing upon the journal `boues of the trailer truck trame, connections between the forward ends of Said springs and the trailer truck iframe, the rear ende of which springs support a portion of the locomotive frame and parts carried thereby, and a removable center bearing between the trailer truck trame and locomotive frame, which center bearing is positioned between the front hanger and the trailer truck axle.

7. The combination with a locomotive trame, of a trailer truck frame, a hanger Y bearing upon the journal boxes of the trailer truck7 connections-between the forward ende of said springe and the trailer truck frame, the rear ends oit which springs support a portion of the locomotive frame and parte carried thereby, and. a pair of removable side beariiflgs arranged. between the trailer truck frame and the locomotive iframe between tlie support at the Vlorward end of said truck frame and the trailer truck axle.v

bearings of the trailer truck frame for supporting the same.

9. The combination with a locomotive frame, of a trailer truck frame7 flexible connections between the rear end of said frame and the locomotive frame, yieldingly supported hangers carrying the forward end of the truck and a combined pivot and center bearing between the locomotive frame and truck frame at a point between said hangers and the trailer truck axle.

l0. The combination withl a locomotive frame, of a trailer truck frame, flexible connections between the rear end of said frame and the locomotive frame, yieldingly supported hangers carrying the forward end of the truck, a combined pivot and center bearing between the locomotive frame and truck frame at a point between said hangers and. the trailer truck axle, and removable side arranged between the locomotive frame and trailer truck frame.

l1. The combination with a locomotive frame, of a trailer truck frame pivotally connected to the locomotive frame at a point between the forward end of said truck frame and the trailer truck axle, an equalizer bar yieldingly. carried upon the locomotive frame, and means for selectively supporting .theforward end of the truck frame at one or more points from said equalizer bar.

l2. The combination with a locomotive frame and a trailer truck frame, of means for selectively arranging the points of support between said truck frame and the locomotive frame, and means for selectively loeating the points of application of the load to said truck frame. y l 13. rlhe combination with frame and a trailer truck frame, of means for varying the points of support between the forward portion of the trailer truck frame and the locomotive frame, and means for selectively locating the points of application of the load to said trailer truck frame. 14. The combination with a` locomotive frame7 of a trailer truck connected to said locomotive frame, a member yieldingly supported upon the locomotive frame, and means for selectively supporting the forward portion of the truck frame at one or more points from said yieldingly supported member. A

lThe combination with a locomotive frame7.of a trailer truck frame pivotally connected to the locomotive frame, journal boxes for the trailer truck axle, springs supported by said journal boxes, tween the forward ends of said the trailer truck a locomotive springs and frame, and friction inem with the rear ends of said springs for supporting parts carried by the locomotive frame.
